G'day janielynn, and Welcome to linux.org
Is this your flex 10 ?....I am asking so we will know what the specs are...eg hard drive size (32 or 64 GB ?)
etc etc.......it runs windows 10 , so it should have ample power.
may I ask why you are switching to Linux ?
have you used Linux before ?
have you looked at any of the Linux distributions (operating systems)...most often called 'distros' or OS)
Can you tell us what you use the flex 10 for....Just normal browsing, YouTube, pics, music, videos .etc etc.??.....tell us if you use it for anything unusual or specific.
This will give us an idea which OS to recommend for you
